With the U-ONE Compact (UOC 40) Johannes Hübner Giessen is raising the bar for simultaneous position and speed monitoring solutions in the heavy-duty applications to a new level of performance. The new universal encoder system not only reduces costs while significantly increasing switching accuracy it also offers a wide range of useful additional functions.

For applications requiring functional safety up to SIL 2 to DIN 61508 and PL d to DIN EN ISO 13849, Hübner Giessen optionally offers the safety-certified version: the U-ONE-SAFETY-Compact (USC 42) featuring two-channel system architecture.

All the functions of the UOC 40, such as up to 15 programmable relay outputs and real-time position and speed data, are combined in a single compact device that can be attached directly onto the rotary axis to be monitored (for example, a rope drum on a crane). Thanks to the compact combination different electronic function modules, there is now no need for the otherwise usual array of individual devices (absolute encoder, speed switch, rotary cam limit switch) or additional mechanical components such as distribution gears, couplings, and speed step-up gearing.

This translates to a significant reduction in investment, maintenance, and installation costs while at the same time allowing you to improve system accuracy and implement useful additional functions. The UOC 40 guarantees rapid availability following initial installation, maintenance work (e.g., changing ropes) or replacing devices, for example the time-consuming work setting cam disks for mechanical rotary cam limit switches is now a thing of the past.

The accompanying software makes it easy to configure parameters (optional before or after installation) as well as accept data defining position switching points directly from the application. Thanks to the ability to save parameters it is easily possible import data, for example when replacing devices. Following installation or repairs it is possible to harmonize the internal coordinate system of the UOC 40 quickly and simply with the application via the pre-set input.

The UOC 40 offers a high level of switching accuracy, thanks to the 28-bit resolution, an adjustable switching hysteresis as well as configurable relay outputs for position, speed, or deployment as a fault switch. Optional real-time data for position and speed monitoring are available via an analogue 4-20 mA output, an incremental output or bus interface, e.g., PROFIBUS or PROFINET.

The internal diagnostics system of the UOC 40 permanently monitors the entire system for possible illegal deviations in the status and actively signals this via the digital status and error output for further evaluation by a connected PLC. Alternatively, it is possible to directly integrate an emergency stop circuit via a relay output configure as a fault switch. The high level of functionality of the UOC-40 is rounded off by the operating status being indicated via LEDs as well as a status and error output, a simple error reset via the reset input and low inspection requirements thanks to an integrated switch test function.

The U-ONE-Compact offers the following advantages:

• Extremely economic thanks to the low overall operating costs
• Attractive purchase price
• Simple to install
• Time saving start-up
• Low standstill costs during maintenance tasks
• Long service life
• High levels of availability in extreme operating conditions
• Robust housing
• Degree of protection IP66
• High shock and vibration resistance
